headlamp operation and control
As described above, the main casing 100 of headlamp is for providing shell for the control circuit of headlamp and power supply.According to various embodiments, control circuit can be for controlling the LED230 of headlamp, the integrated circuit of 240, and power supply can comprise rechargeable battery pack or disposable battery.In various embodiments, the control circuit of headlamp is set to have multiple light illumination mode, changes the various aspects of the light launched from the LED230,240 of headlamp.Such as, in one embodiment, the control circuit of headlamp has following light illumination mode: (1) high constant luminance pattern, (2) low constant luminance pattern, (3) automatic dimmed pattern, (4) flash mode, and (5) ruddiness pattern.As used herein, high and low appointment is comparatively speaking, and high constant luminance pattern is more constant than low constant luminance pattern, instead of means any specific brightness degree.As hereinafter by describe in detail, user can utilize the button 120 of headlamp to switch between multiple light illumination mode.
According to various embodiments, adopt the control circuit in high constant luminance pattern, main LED230 has the visible ray of relatively high, constant luminous flux (as 200 lumens) and high luminous intensity (as 4325 candelas) by launching.As a comparison, adopt the control circuit of low constant luminance pattern, main LED230 has the visible ray of relatively low, constant luminous flux (as 15 lumens) and low luminous intensity (as 342 candelas) by launching.In low constant luminance pattern, the luminous flux of the light that main LED230 launches is less than the luminous flux of the light launched when main LED230 is high constant luminance pattern.In high constant luminance pattern and low constant luminance pattern two kinds of patterns, substitute LED240 does not light, and the luminous flux of main LED230 can not regulate according to the feedback of photoelectric sensor 250.But in any one pattern, the luminous intensity of main LED230 can regulate by rotating flange 231, thus at the light that less region or larger zone focusing are launched.
When switching to automatic dimmed pattern, according to the signal of telecommunication that the photoelectric sensor 250 mentioned above produces, the grade of control circuit monitoring headlamp 2 surrounding environment light.Control circuit regulates the output of main LED230 automatically subsequently, makes the ambient light level that this output detects corresponding to photoelectric sensor 250.Such as, when control circuit detects that the grade of headlamp 2 surrounding environment light declines, the electric current supply that this control circuit will make power supply increase to main LED230, thus increase the luminous flux of the light launched from main LED230.Similarly, when control circuit detects that the grade of headlamp 2 surrounding environment light rises, the electric current supply that this control circuit will make power supply be reduced to main LED230, thus the luminous flux reducing the light launched from main LED230.By this way, headlamp 2 can automatically regulate the light intensity of launching from main LED230.
In flash mode, control circuit makes main LED230 glimmer (e.g., by intermittently launching black light and the visible ray of constant luminous flux).In this mode, the LED240 that substitutes does not light.In ruddiness pattern, close main LED230 and open substitute LED240, to launch the visible ray in red spectrum, this visible ray has constant luminous flux (as 2 lumens).Correspondingly, in ruddiness pattern, be only transmitted in the light within red spectrum, and headlamp 2 can illuminate the surface near user, and the eyes of user can not be caused significantly to regulate and weaken night visibility.
